Title: new JBP
Post by: Jason E on April 26, 2012, 07:13 PM
Hello all,

Thought I'd share a pic of a JBP that I finally brought home. It was repotted about 6 weeks ago from an Anderson flat, bare rooted 1/2 and potted in clay king. The pot it's in now is temporary until I find something nice for next repot.
planning on cutting back some branches and reducing to two shoots when time for de-candling, letting them go till then to promote root growth.
thoughts, suggestions?

Thanks, Jason

Very nice!  When you say you "finally brought it home", is it one you've had your eye on for a while, and now finally pulled the trigger to buy?  If so, congratulations!  It looks great!

Now, if this were my tree, I'd study it and decide which are my "keeper" branches, and which are the sacrifices.

Treat them differently:

Keepers:  I would say this is not the year to decandle.  Use decandling as a technique when you get more refinement.  This year, I would cut back into last year's growth to promote back budding.  On the branches you want to shorten, you can cut off more than just this year's candle, cut back into last year's.  Where the wood is tan.  Be sure to leave some needles.  You will get needle buds developing between the needles you leave on.

Sacrifices:  Leave this year's canldles alone.  Let them grow.  Strip off old last years and previous year's needles.  This will allow light to get into the center of the tree to help promote back budding.

Thanks adair, very helpful info :)  I bought this guy a while ago but left it at the nursery following the repot. It;s warming up a bit here now so finally brought it home. how about timing for working on the branches to be kept? I'd like to get the most second growth/budding this year as possible which seems like early might be good. I guess what I'm asking is would later cut back,(mid-june) result in less secondary growth?
ddoes that make sense?

Thanks again, Jason

where did you get it? Teleperion Farms? Awesome tree looks to have great potential

You could do it now.  When JBP needle buds develop from year old wood, they are not really very vigorous.  And you're not concerned about reducing needle length at this stage, so doing it now would allow for a longer growing season for your new buds to develop.

Make sure to leave 5 to 7 pairs of needles.  You'll probably get buds on at least 3.  Then you can pick and choose.

I have seen techniques illustrated in Japanese magazines where they try to be more selective.  That is, they figure out exactly where they'd like to have a future twig, and leave a needle pair there, but strip the others close by.  Stripping the needles destroys the buds, so no future twig there. They only get buds where they left a pair of needles.  I don't know if that really works, I've never tried it. (It probably does, or else it wouldn't be published in the JBP "technique" book.)  I do know that leaving a bunch of needles at the end will result in several needle buds (a cluster, maybe?) and then you can pick and choose the ones you want to keep.

Needle bud growth looks different than candle growth when it first emerges.  Your pine looks really healthy, so they may grow rather long.  If they get more than an inch, you may consider pinching them back a little.  But, that's a couple months away.  Eventually, the branch developed by a needle bud will look like one produced by a candle, and it will produce candles as well, and you would treat it like any other.  The first year, it will look a little different.

Very nice tree JMEK!  Will be a real showcase when finished.

Nice start. I would suggest a few simple things this year. I would suggest reducing the number of spring candles to two. At each branching. On te upper parts of the tree, break the really long candles, break them so at least a few of the needle buds remain to produce needles. You can also cut the old needles in half using scissors, the od needles are those not in the growth from lat year (just below the elongating spring candles). This is a relatively young tree, can tell by the bark, if you fertilize it strongly, get some sunlight in to the interior and water it well it should pop buds up in side quite readily. Wiring the tree next winter will also help to open the tree up and stimulate back budding.

Good choice.

That's one good-looking tree, Jason: fine base and trunk, in particular.

I'll be watching its progress with interest.

Thank you everyone!

Nathan, I got this tree from Bonsai Northwest in seattle. Helped dig a bunch of them from the field this spring, there will be some nice ones available soon.

thanks again,
